A heterosexual girl or woman who partakes in any sort of sexual or promiscuous activity with another female to get attention from males. This usually takes the form of making out, and to a lesser extent, grinding or dry humping with another female.

This is a common sight at bars (hence the word barsexual) but can also be found at any party, especially frat parties.

The reason for such acts has baffled researchers for years, but it is thought that they seek attention, free drinks, or are prudes too scared to get with men.

Dude 1: Oh shit, check out those lesbos making out bro!!!
Dude 2: No you idiot, those are barsexuals.
Dude 1: Damn, you're right. Sluts!!!

College girls who make out with each other at a party for any of the following reasons: (1) They are being hit on by sketchy sketchy men (often stoners or past hook-ups) and they need a cute and permanent exit strategy, (2) the party is lame and they feel the need to entertain, (3) they are very very drunk, (4) they are convinced by horny men with cameras.
*If any of the following situations arise during your own barsexual display, you must either stop and leave the party immediately or enter the witness protection system the next day as those pictures will be going up on facebook whether you like it or not. Try to avoid situations where dirty, horny men are either cheering you on, telling you they don't believe you did it and asking to see it again, are counting the number of seconds you can make out for, or have convinced you that making out with her topless is the only way to do it.

"I was a little confused about those couple incidents at the beginning of the semester. I didn't know if that made me bisexual or just an attention whore. Now I know: I'm just a barsexual"

Any inane girl/guy (mainly girls) who think that pashing their best friend/another chick in a pub/club in order to give the impression that they are bi-sexual - is cool. Usually done to titillate a boyfriend or male onlooker with no intention or desire to follow through with same-sex actions. Pseudo-sexual behaviour of the lowest order. Should be exposed for the sexual fraud it is.

Usually localised to a bar or the like and same 2 chicks would never kiss elsewhere.

"look at that guy over there, do you think he will notice if we pash?"
